removing headless nails old window boards

[makp]

help!, have tried to remove old window boards but am only suceeding in knocking out adjacent plaster as i am struggling to remove the headless nails, have tried to use a cats paw by chiselling away at adjacent timber but the movement (to the timber gounds beneath is causing the plaster to crack away.....can i drill th nails out or something else ?

You could use a small diameter hole saw so the nail is between the centre bit and the outer blade.Drill out a core around nail lift the board and remove nails.

thanks for the idea...had n't thought of that...but just realised that i need to slide the board out horizintally as its slotted beneath the plaster of the window reveals

You could try a mole grip to clamp on the nail to pull it out. Try a screwdriver under the jaws to lever the nail out.

Use a thin punch and drive the nail right though the board or alternatively use a hacksaw blade to saw though the nail on the underside of the board.

thanks all for the suggestions, unfortuntely i don't have access to the underside.....i'll have a look if we have a mole grip in the shed and give that a go.
